Hello everybody, since a few weeks back after a power outage in my house I´m not able to start my vms with my gpu (NVIDIA 1080Ti), this is the error that I get:

 

qemu-system-x86_64: -device vfio-pci,host=0000:01:00.0,id=hostdev0,bus=pci.5,addr=0x0,romfile=/mnt/disk1/isos/vbios/gtx1080ti.rom: Failed to mmap 0000:01:00.0 BAR 3. Performance may be slow
2022-01-24T12:13:08.849907Z qemu-system-x86_64: vfio_region_write(0000:01:00.0:region3+0x40a8, 0x2bffaf01,8) failed: Device or resource busy

 

Any ideas?

 

Th GPU is working fine when I connect it to other machine

 

Thanks

Did you try a search in this section of the forum?This topic has been covered several times.

append video=efifb:off initrd=/bzroot

 

I dont know if that is gonna work for my

If you are booting unraid in uefi mode, if in your syslog you find errors like bar x can't reserve, device or resource busy, if you run cat /proc/iomem and you will find efifb listed, then probably yes, it's the solution.

It was, thank you for your help!

Can you please add where to add the code for the solution?

Thanks!
